TALK=T;RUN(1,1) DISPLAY This case concerns axisymmetric incompressible laminar/ turbulent flow in the expanding pipe. The flow exhibits recirculation not only behind the step at the pipe wall, but in the region on the pipe axis. Calculations of the turbulent flow (LTURB=T) could be made with low-Re extensions of whether standard K-E model (LOWKE=T) or Chen-Kim K-E model (LCHEK=T). User can switch from the default colocated computational algorithm (CCM) to the staggered one (STAG) by setting LCCM= F. --------------------------------------------------------- ENDDIS PHOTON USE p ;;;;; set vec av off msg Velocity vectors: vec i 1 sh msg Press any key to continue ... pause cl msg Pressure contours: con p1 i 1 fi;0.01 pause msg Press any key to continue ... cl msg Swirl velocity contours: con uc1 i 1 fi;0.01 pause msg Press any key to continue ... cl msg W-component contours: con w1 i 1 fi;0.01 msg Press any key to continue ...
